LOOM SHUTTLE.

i Application filed November 16, 1925. Serial No. 69,520.

To all whom t may eonoem: l

Be it known that I, CHARLES HENRY WIL- KINsoN, a subject Yof the King of Great Britain and Ireland, residing at Leigh,

Lancashire, England, lhave invented new' .for threading the shuttles by hand and preventing threading by the mouth.

According to the invention, the shuttle is provided yon its top side and at the end usually furnished with the thread eye, with a deep'circuiar depression, large enough to admit the finger of the hand. In one side of the shuttle, and opening into said depression, is a circular hole or opening, which is extended at one side to form a narrow slit, running parallel with the longitudinal axis of the shuttle, the hole and slit forming` a key-hole shaped slot. Lying across said slit is a forked pin, or stud,.m`ade of metal, porcelain, or other suitable material, the opening of the stud lying in a plane at right angles to the side of the shuttle. One limb of the stud is slightly shorterv than the other, and is rounded and slightly turned inwards, and that part of the shuttle into which the lower end of the stud projects, is cupped out or recessed, and is slightly larger Athan the stud, thereby leaving a space, or clearance, around the lower end of the stud. Extending from thev said circular depression to the usual opening for the shuttle tongue, is a groove or channel, through which the weft may pass from the cop.

In threading the shuttle, the weft is drawnv off the cop and made into a small tuft or ball, which by means of, say the first or index finger of the weavers hand, is pushedy into the said vertical depression, Vfrom which 'it can be readily drawn by hand through the hole in the side of the shuttle. Y

On the shuttle being then placed in a loom, the first pick causes the weft thread to pass into the narrow extension of the side hole and slip below the shorter limb of the said forked studand between the forks of said stud, from which position the weft cannot escape, while free to be drawn out of the shuttle in the weaving operation.

To prevent undue abrasion of the shuttle, a further forked metal, or porcelain, stud, is 'applied to the groove leading from the cop opening to the said depression, and to provide for a slight drag on the weft, said forked stud has overlapping formations on its inner faces.

The improvements allow of the shuttle being used right or left hand, and for weft way, or twist way, or twist way weft.

Upon the accompanying drawing:

Fig. l illustrates a side elevation.

Fig. 2 a plan view, and

Fig. 3 a cross section of shuttle with the invention applied.

Figs. l and 5 illustrate perspective views of a part of the same shuttle, portions being broken away in Fig. 5 vto show the invention more clearly. f

Fig. 6 illustrates a detached side view of the forked stud vwith one limb shorter than the other. f

Fig. 7 illustrates a detached side View of the stud used in the groove between the cop opening and depression.

Figs. 8 and 9 illustrate in side elevation and plan a modification of such groove stud, while,

Figs. 10 and 11 illustrate like views of a further modification. v

Fig. 12 illustrates a plan of a modfication of Figs. l() and 1l.

a is the body of the shuttle, while b is the usual space for the weft cop and c the spring tongue. (l is the large vertical depression extending from the top face of the shuttle to a point below the level of the tongue o. e is the key-hole shaped opening in the side of the shuttle. 7 is the groove be- F ig. 3, and the inner faces of the bifurcations lying parallel with the sides of the y groove, see Fig. 2.

ln the top face of the shuttle, Ynear to f one side of the shuttle, is formed a recess in which is fitted the forked metal or porce` lain, stud which-virtually constitutes thel eye of the shuttle, see Fig. `1. Such stud entends across thenarrow part of the opening e, and its bifurcations extend downwards, see Fig. l. One limb of the stud is` shorter than the other and is slightly bev 'tions of the studextending upwards, see

elled on its outer side and curved inwards, see Fig. 6.

Further, the slot formed by the bifurcations is ot' key-hole shape, and the round part eoines opposite the narrow part ot the opening` e, see Figs. l, 3 and 4. That part ot' the shuttle encircling the lower end ot the shorter iinib of the stud ent away to Vtorni a .small Cavity and to allow the we tt. to pass below said shorter liinb ot the stud when threading the shuttle.

The studs, when made of metal, wfll preterably be toi-ined in one with a torled extension or bitureated rivet', whereby the stud may be tirmiy secured in postion (see Fig. Il) with or .vithout the aid ot an adhesive. ll'hen made olf porcelain, the studs will be iined in position partly by being a tight lit, and partly b v meal i et glue.

ln threading thel inutile, a small Quantity ot' weit is drawn oliA the cop and rolled into a tuti or ball, by which the wett lirf in the groove f and between the l ii`u1 'eati nis ball, is then'inot the stud (,f. The tul't, o" sert-ed by means oit the ot one 'hand` into the depression (Z, and pushed down until it comes opposite the opening n, when it is nipped by the linger and thumb and vpulled through such opening, as shown dotted in Fig. 2. Using ythe tutt, or ball, as al handle, the wett is then drawn baci;- 'wards and tensioned with a sharp pull, which causes it to slip below the shorter liinb ot the stud 71 and pass into the slot formed by he bifurcations of the stud, and finally lie in the round part of the slot, see Figs. l, Q and when the shuttle is fully threaded and ready ilor use. The tensioning ot' the wett to Cause it to pass below the shorter limb of the stud 72y need not be done by the weaver, but inay bo done automatically in the looin by the first or seeond piek ot the shuttle.

In this way the necessity to thread the shuttle by the linouth is dispensed with, and moreover, the threading ot the shuttle bv the mouth is prevented, as the holes are too large to allow of the threading being` done by suction. After being threaded. the shuttle cannot beeoine unthreaded as the shorter liinb ot' the stud 71 and the .snrrounding parts of the shuttle, torni an ell'eetual trap.

As a inodiieation the groove stu-d y shown in Figs. 8 and 9 is loi'ined with the bifurcation out of centre and-opening tangentially into a central hole. It recois or groove 7J is torined on the Afront aee ot the stud leading to the hole. rlhe stud is designed to trap the thread to avoid trouble from 4coming out by ballooning the thread being caught. in the groove should it atlii tempt to rise in the stud.

To afford an additional drag on the wett, the stud g niay De lnade as shown in Big5.
